What are podosomes?
What are podosomes? Podosomes are actin-rich, adhesive structures that are present at the ventral surface of cells of the monocytic myeloid lineage, stimulated endothelial cells [1] and cultured Src-transformed cancer cells. These structures are [...]
What is the first step in podosome assembly?
What is the first step in podosome assembly? Podosome initiation and assembly is highly regulated, both spatially and temporally. Dendritic cells best exemplify the temporal regulation of podosome formation. Following activation by an antigen [...]
What mechanisms drive cytoskeleton extension within podosomes?
What mechanisms drive cytoskeleton extension within podosomes? Interactions between the extracellular matrix (ECM) and cell surface integrins leads to podosome formation. The initiating signal is transduced through mechanosensing integrins to the cytoskeleton, upon which [...]
What are stress fibers?
What are stress fibers? Stress fibers are higher order cytoskeletal structures composed of cross-linked actin filament bundles, and in many cases, myosin motor proteins, that span a length of 1-2 micrometers [1]. At least [...]
What are the functions of podosomes?
What are the functions of podosomes? Both focal adhesions and podosomes are intimately involved in cell motility, with podosomes specifically implicated in cell invasion. Invasiveness is achieved through the secretion of matrix metalloproteinases (MMPs) [...]
How is stress fiber assembly regulated?
How is stress fiber assembly regulated? Tension-dependent actin polymerization and assembly of stress fibers is influenced by many factors (reviewed in [1][2]), including differences in substrate composition [3], rigidity [4][5][6] (reviewed in [7]), cell [...]

Cell-Matrix and Cell-Cell Mechanotransduction, Molecular Mechanisms of Mechanobiology
Wei Yung’s interest lies in understanding the sophistication of cells as robust machines. Using C. elegans, a 1mm nematode, as a model system, he investigates the cellular machinery underlying newly fertilized zygotes that drives critical force-dependent processes such as polarization and cytokinesis.
Biography
Wei Yung completed his Bachelor’s degree in Bioengineering (Second Class Upper) from the National University of Singapore in 2012. In his honors dissertation under the co-supervision of Professor James Goh and Professor Wong Hee Kit, he optimized the conditions required for the construction of interbody spinal fusion device using primary adipose stem cells seeded in a biodegradable polycaprolactone/tricalcium sulphate (PCL/TCP) scaffold. The work was presented in the Bioengineering Showcase 2012 and he was awarded the Best Poster Award. After he was enrolled in the Mechanobiology Graduate Program, he joined Dr. Zaidel-Bar’s Cell Adhesion and Morphogenesis Lab and is currently searching for novel genes involved in regulating C. elegans early embryogenesis.
